coMroU'ND RAIL.

Be it lrnown that I, OLIVER C.' THOMPSON, a citizen of the UnitedStates, residing at Phoenix, in the county of Maricopa Vand State ofArizona', have invented certain new and useful Improvements in CompoundRails, of which the following is .a specification. Y

This invention relates to railroad rails and'more particularly to'compound rails.

One of the principal objects of the invention is to provide an improvedcompound 'rail adapted to be easily assembled and disassembled forrenewal of worn parts, and adapted to be maintained in locked posi-.tion by vaction of the car wheels passing over'the rail. A furtherobject of the invention is to provide a compound rail including aresilient ller upon which a tread portion in the form of a cap or facingplate is locked, said cap or facing adapted to be removed when VAnotherobject of theinvention is to vprovide an improved compound railwhichwillbe extremely simple, durable, eflicient in operation and inexpensive tomanufacture.

With these and other objects in' view which will become apparent as thedescription proceeds, the invention resides inthe construction,combinationk and arrangement of parts, hereinafter more fully describedand claimed, Yand illustrated inthe accompanying drawing, in which likecharacters of reference indicate like parts throughout the severalfigures, of which Y Figure 1 represents a view in side elevation of arail constructed according to my invention, parts being broken away toexpose the interior structure thereof. Fig. 2 represents a top plan view.of a rail constructed according to my invention. Fig. 3 represents avertical transverse sectional view taken 'on the plane indicated ,by theline 3 3 of Fig. x 1. Fig. 4 represents a fragmentary perspective viewof adjacent ends of lockingbar sections showing the construction ofthesame. Fig. 5 represents a fragmentary vertical sectional view,showingone of the locking bars as equipped with aneyeboltg` f 1 Incarrying out my invention I provide a roadbed or traclrway indicatedgenerally at 5 and formed of concrete or other composite or monolithicmaterial. The adaptation of the rail for use with such a road-bedrenders i 4'Speeiication of Letters Patent.

the fformer of particular "use in paved streets, yalthough it will beunderstood an independent base or traclrwayy may-be constructed. Thebase or roadlbedv is .channeled as at 6 for the reception of thetrough effra1ea1eu ret. e, 191e; appiicationiedaprnso,1915. seriainazassa" 7.The latterincludesa floor 8 disposed horizontally, a verticalouterwallf9 whose upper portion 10 is olf-set inwardly from the Alowerportion thereof so that a shoulder llis formed at, any desired height onthe outer wall,and an inner wall12. VThe latter Y is disposed ata slightangle and bears away from the outer wall. The side walls 9 and.

12 Lare provided withoutwardly extending horizontal flanges "13 and'lcrespectively,

whose upper'surfaces lie flush with the-upwheel. Stamped from the anges13 andflfi either at.-the`I ends thereof or intermediate their endsor'both, are the depending substantially vertical anchor bars'orstrip's'l.

The latter depend alongside and in spacedV relation to the'walls of thetrough andare embedded inthe road-bed for anchoring the trough-rigidlythereto.. .V .Y

Adapted to be disposed within is a wooden or other resilient filler 17crowned with a facingvorl tread plate 18. Filler 17 as indicated may bemade of Vwood `or wood pulp, papier mch, or other suitable materialVcharacterized Vby al certain amount of compressibility or resiliency.`

The bottom` face of the, filler rests :flat

against ioorS of the trough, and is ofy av width somewhat rless than thedistancebetween walls 9 and 12 vfat the lower portion of' the 'latterVThe sides of the filler are substantially vertical, the .upperportion1of1said rillerbeing` reduced so that,

the crown or tread plate 18 `may be dis.-

portion 19 conforming tolthat of any. apf proved rail section depending?froml'which and at right angles thereto :are lside flanges lies flushwith theadjacentv face22 lof the filler. yThe lower` edge .of depending,flange 21l is flared outwardly-'at 23 and rests in a concaved surface214providedinv the outer'.` face of filler 17. V,The flared portion 231isadaptedV tol vbe locked yinto position ,with i 2O and 21. The outerface' ofthe former shoulder 1l by means of a wedge bar 25to preventvertical movement of the filler and crown plate relative to the trough.

The wedge bar 25 is provided with a vertical face 26 adapted to lie fiatagainst the outer face of depending Harige 20 and the adjacent face 22of the filler. The opposite edge or face of the wedge bar is inclined,so that when the bar is dropped between the filler andl wall' 12 of thetrough, there may be a wedge action between wall 12 and the wedge bar,whereby the filler together with its crown plate are wedged against theopposite wall 9 of the trough and locked in fixed position with saidtrough by reason of the shoulder 1l and fiared flange 23. When the partsare in this position a slight space indicated at 27 is left between thelower edge of the wedge bar and the iioor 8 of the trough, so that ifthe filler and the crown plate should wear on their lateral faces thebar may gradually work downwardly so as to always maintain said fillerand crown plate in locked and immovable position.

It will be noted that the upper edge of lock bar 25 occurs adjacent `thelower edge of curved portion l5 of the inner wall of the trough, so thatthe car wheels in rolling over the rail may contact with said lock barfor maintaining the same in position. The relative position of the carwheel with therail is indicated in dotted lines in Fig. 3.

The trough, filler, crown plate and lock bar are made in sections whichare assembled end to end in constructing a track, but the'joints thusformed in the separate pieces do not occur at the same places, but areplaced at various intervalsto each other. For instance, in Fig. 2 thetransverse dotted line 2S indicates the joint between two fillersections, the transverse line 29 indicates the joint between two crownplate sections, and the transverse line 3 0 indicates a joint between'two wedge bar sections. rlhe ends of. the wedge bar sections are asindicated in Fig. 4 provided with interlocking lugs andV recesses 31 and32 respectively, of'a shape similar to that indicated, or of some othersuitable shape, so that separate verticalv movement of any singlelock'bar section after the track rail is assembled is thus prevented.

When any crown plate becomes worn and is to be renewed, the adjacentwedge bar sections may be lifted, and the old plate removed Vand a newone putr into place upon the old filler, whereupon the bars will bedropped back into position. The'arrangement provides for the expansionand contraction of the various metallic parts due tothe changes intemperature, since the wooden or resilient fillers will accommodateslight changes in dimensionsofthe metallic parts due to either expansionor contraction. No fastenings which are often times eXpensive'tomanufacture and require careful and frequent watching are used with myrail, the only adjustable part being the wedge bar, which as beforestated is maintained in place mainly by the action of the passingwheels.

In order that the wedge or lock bars may be raised when necessary, eachof them is provided. adjacent one end with a threaded opening or socket33, normally occupied by a threaded plug 34. The plug is provided with agroove in its upper end whereby it may be engaged by a screw driver orsimilar instrument for removal. Vhen it is desired to remove a sectionof the bars the desired plugs may betaken out and eye bolts 35, as shownin Fig. 5, may be substituted for them, thusV affording a medium wherebyany suitable lifting force may be transferred to the bars.

yAlthough I have described the preferred embodiment of my invention, Imay desire to make such changes in the construction, combination andarrangement of parts thereof as do not depart from the spirit of theinvention and the scope of the appended claims.
